OPTION1 - netTIMS-System Easily expandable experiment platform for advanced experiments. Completely customizable experiments, pre-wired by the professor and remotely controlled by the student.Over 200 advanced experiments covering analog and digital modulation, codingplus signals & systems topics.
net*TIMS allows professors to set-up real TIMStelecommunications experiments in their own laboratory, whichstudents can then access and control from within the lab and at adistance, to carry out the experiments.
net*TIMS-enabled modules have switches and potentiometerswhich are remotely controlled via Ethernet. The net*TIMS-enabled modules are plugged into a standard Emona TIMS-301System Unit and are patched to the net*TIMS Server, which isconnected to the LAN/Internet via an Ethernet port.
The GUI at the user PC mimics the experiment front panels anddisplays acquired real signals, using a digital 2 channeloscilloscope from 8 different points in the experiment for eachchannel. 4 trigger points are also available.
All waveforms can be viewed in both the time and frequencydomain.
SIMPLE BROWSER LOG-ONA user logs on to the net*TIMS Server using their web browser.They receive a JAVA-based client screen, as shown to the right,corresponding to the particular experiment set up on thenet*TIMS System.
• Students control real TIMS hardware from theirPC and obtain immediate PC-scope display ofthe real signals
• Remote control of hardware via GUI
• Flexible experiment patching
• Fault insertion capability for student debugging
• 24/7 access to real TIMS hardware experimentsvia browser/client
• Real-time logging of student experimentprogress and access
• Collaborative learning Environment for students

EMONA net*TIMS-System
Why consider remote controlledhardware experiments instead oflower cost simulation software?
Because students do learn better:they find the results obtainedfrom hardware systems more
believable.
Experience shows that studentsdon’t believe and question thevalidity of unexpected results
obtained from simulationsoftware.

net*TIMS SERVERA web server unit which ‘serves’ the net*TIMS EXPERIMENT SCREEN toeach user ‘client’ software, as well as housing the digital scope andmultiplexer used to capture actual signals for display.
net*TIMS Scope InputsReal, multichannel digital storagescope. Captures users’waveforms.
EASY ACCESS TO ALL TutorTIMS FUNCTIONSEmona net*TIMS-System overview
The student can simultaneously access other course materialprovided by the professor and also transfer actual experimentalresults between the net*TIMS screen and other applications tocreate Lab reports.
The user can switch, insert or by-pass hardware modules in theexperiment, as set-up by the professor, for multi-stageexperiments.
MULTI-USERThe net*TIMS Server manages a multi-user environment,allowing several students, each at a different location, to be
logged onto the same net*TIMS Server and independentlycarrying out their own session of the same experiment.
COURSE MANAGEMENTThe net*TIMS Server provides gate-keeping access and a log ofall student activities. The professor can manage the net*TIMSServer from a password protected administration page via theirbrowser.
Ethernet PortThe ethernet port at the rear of the net*TIMS Server providesuser access via PC, or LAN, or Internet.
net*TIMS Enabled Plug-in ModulesHardware modules are patched together following exactly theexperiment as displayed by the net*TIMS CLIENT software. Allknobs and switches are controlled on-screen by the student viathe net*TIMS CLIENT running on their PC.
Professor’s PCConnected via ethernet port to the LAN,to access the net*TIMS experiment andalso the Server’s ADMIN pages.
